HEATER.

Application filed April 12, 1926. Serial No. 101,254.-

This invention relates to' heaters of the kind in which air is taken in at the bottom and discharged in heated condition at the top of the heater, means "of any suitable character, such as a gas burner or other heating element, being enclosed within the body of the heater, so that the air is heated as it passes upwardly inside the heater body.

This is an improvement upon the form of heater shown, described and claimed in prior application No. 46,062, filed July 25, 1925. An object of the invention constituting the improvement is to provide a construction in which the maximum heat will be at the front of the heater, while the minimum temperature will be at the back thereof. so that the heater may stand upright against or close to a wall, without danger of burning or overheating the wall.

Another object is to provide a novel and improved construction involving the use of flat walls practically throughout the entire structure, and to reduce the costof manufacture.

It is also an object to provide certain details and features of construction, and combinations tending to increase the general efficiency and the desirability of a heater of this particular character.

To the foregoing and other useful ends the invention consists in the matters hereinafter set forth and claimed, and shown in the accompanying drawings, in which, Fig. 1 is a front elevation of a heater embodying the features of the invention ,Fig. 2 is a verticaLsection on line 22 in F sl in Fig. 1. e

' As thus illustrated, the body of the heater comprises fiat, upright front and back walls 1 and 2,; and the flat side walls 3, forming a hollow, upright body having a flat top wall 4 and a flat bottom wall 5, as shown. Said top wall is provided with air outlets 6, and the said bottom wall is provided nith air inlets 7 and 8, as shown. The. flue 9 extends upwardly within the body, and is inclined toward the front of the body, as shown. This flue forms a hollow partition within the body, dividing the interior of the body into a front compartment 10 and a rear compartment 11. As shown, the said flue is open at its upper and lower ends, and its front wall is profvided with inlet open- Fig. 3 is a horizontal section on line 33' iron corner members li of the'body, with space between this plate and the top wall 4, and with the rear portion of said plate turned .down to form the back wall 15,

whereby the space betwQen the plate 13 and the wall 14 is open at the front, of the heater and also at each side thereof, but not at the rear. The said angle-iron members 14:. are extended downward below the body of the heater to form the legs 16 thereof. A bafile plate 17 is preferably provided a distance below the bottom wall 5 of the heater, so that air may enter thelower end of the flue 9, and also through the openings 7 and 8, in

the manner indicated by the arrows. A gas burner '18, or any other heating element, is preferably provided, as shown, in the front compartment 10, near the lower end of. the flue, whereby the air in the flue will be highly heated by the transmission of-heat through the. frontwall of the fine, and whereby the air entering the compartment 10 at the bottom thereof will be heated, and will be discharged, with any gases or prod ucts of combustion, from the top of the front compartment through the openings 12 into the upper end of the flue.

Thus the air entering the bottomof the flue, and the air entering the bottom of the compartment 10 is all finally brought together and commingled'in the space between the wall 4; and the plate 13, and then discharged laterally fromaid space. Also, the

air entering at the bottom of the compart ment 11 will be heated in this compartment,

in the compartment 11 will be much. less than that in the front compartment 10, of course, and in this way the heater Wlll practically have a 0601 back which can stand against a wall withopt danger of burning or overheating the wall.

Of course; the flue 9 extends from one side wall 3 to the other side wall 3, so that the compartments 10'and 11 are n0n -intercommunicating. As the flue is inclined toward the front of the heater, it follows that the front compartment tapers upwardly,

while the rear compartment tapersdownwardly.

A small swinging door 19 is provided, of

' any suitable character, to permit access to and for then discharging the heated air from the top thereof, the combination of a body forming outer side walls and a back wall and a front wall-for the heater, an open bottom flue extending upward therein, an imperforate top plate for the heater, with space between the outside of said flue and the inside of said body,'the heatenhaving inlet means at the base thereof to admit airto the lower end of saids'flue, and also to the bottom of said space, the flue having one ormore inlet openings in the upper front portion maximum thereof to receive the heated air from the upper portion of said space, so that the flue and space intercommunicate, and the upper portion of said heater having meansdisposed above the top of said spaceand below said top plate for commingling and for laterally discharging all of the air which enters ,the heater at the bottom thereof, and which passes upwardboth insideand outside of said flue, in combination with a heating element applied to the lower portion of said flue, in position to heat some 'air directly and some through the wall of theflue, said flue forming a hollow partition wall within said body, dividing the interior thereof into a front compartment and a rear compartment, preventing communication from one compart- ,ment to the other, but with said intercommunication between said front compartment and said flue, and said heating element beingin said front compartment, whereby the heat will be in the front compartment and the rear compartment will be comparatively cool, to permit the back of the heater to stand against or close to a wall.

2; A structure as specified in claim 1, said flue being inclined forwardly, so that it overhangs the heating element, and is closer the front wall of the front compartment at its upper end than at its lower end. a

3. A structure as specified in claim 1, said rear compartment having an'air inlet opening at thebottom and an air outlet opening at its top, and the rear imperforate wall of the the forming compartment. I

4. A structure as specified in claim 1, the front and rear and side walls of the body being flat, the bodyhavin-g flat top andbottom walls, the flat top wall being disposed a distance below said top plate, and the space between the top wall and the top plate being closed at the rear'thereof, but open at the front and at both sides of the heater.

5. A structure=as specified in claim 1, said flue being fiat and having parallel front and back walls,and the flue being open at its upper end to discharge the air from the front compartment upwardly into the space immediately below said top plate.

6.' In a heater, a body forming the outer front and remand side walls of the heater, a flue therein dividing the interior of the body into front and rear non-intercommunieating compartments, the flue being open at its u per end and also at its lower end, means to admit. air at the bottom of each compartment, means to discharge the air from the top of the rear compartment, means to discharge the air from the upper portion of the'front compartment into the upper portion of the flue, so that all air entering the frontcompartment must escape from the top of said flue, and a heating element in the front compartment. V. f

7. A structure as specified in claim 6, and a plate disposed a distance above the top of saidbody, forming a space below said plate for receiving and mixing the air discharged from the top of the rear corn artment and f rom theupper end of the ue' and'front (compartmen 8. A structure as specified in claim 6, said flue being flat and forming a hollow partition extending from one side wall of the body to the other, and inclined forwardly,

the front wall of the rear whereby the-front compartment tapers upwardly, while the rear compartment tapers downwardly, the rear imperforate, wall of i926. n U
